UHK 80: only one battery status shown when using Dongle

[mhantsch]

When I plug the right half into USB, the OLED display shows two battery levels.
When I disconnect USB from the right half, and it connects via the Dongle, then the OLED display only shows one battery level.

It doesn't matter whether I have the two halves connected with the bridge cable or not.

Firmware 12.3.3.

Is this a new regression or an old one? :-)

[mhantsch]

I don't know, I've never used the Dongle much. Also, I didn't find a previous older issue for it, so I thought I better report it.

This issue isn't related to the dongle. Please confirm, @mhantsch.

05f971b introduced this issue. When the right half is not connected via USB, only the left battery percentage is shown.

It doesn't matter whether the bridge cable connects the halves.
